Beyonce put on a special performance at the United Nations General Assembly Hall in New York yesterday, and the live video footage of her singing her 4 album cut "I Was Here" will be officially released on World Humanitarian Day, which is Aug. 19. Beyonce looked stunning as ever in a gorgeous white gown, as you can see in the pictures above. Supposedly, Beyonce has also been in the studio recently working with Kanye West and Hit-Boy. Stay tuned for the official "I Was Here" live video drop.
